The Dismembered bodies of at least nine people have been found in coolers inside a Tokyo man’s apartment. According to the Associated Press, Takahiro Shiraishi, 27, has allegedly confessed to killing and dismembering the victims and hiding their body parts in cold-storage cases covered with cat litter.

"I killed them and did some work on the bodies in order to hide the evidence," the suspect told police, according to Fox News.

Police made the gruesome discovery this week while searching for a 23-year-old woman who had disappeared one week prior. Police believe she was one of Shiraishi’s victims. Police found the bodies of seven other women and one man in the apartment.

Severed heads were found in coolers, according to the AP. Police spotted a saw they think may have been used to cut up the bodies. Shiraishi allegedly told police he dismembered his victims in his bathroom before discarding some body parts in the garbage, the Kyodo News agency reports. Shiraishi’s neighbors noticed “foul smells” near his apartment lately.

“I thought it smelled like sewage,” one neighbor said. “It was something I never smelled before.”

The AP reports that the missing woman met Shiraishi over a website for people with suicidal feelings. The two were spotted on security camera footage nearby the suspect’s apartment, Japanese public broadcaster NHK reports.

Japan has one of the lowest crime rates in the world. But, lately the country has been ripe with tragic, high-profile murders. In July 2016, a 27-year-old former employee at a care home for the disabled killed 19 people and injured more than 20 in a knife attack. Just this month, a man allegedly killed his wife and five children after setting their home on fire. In 2015, a man killed five people, including relatives and neighbors, in another knifing spree, according to the AP.
